Donna: In my opinion, what you are getting at is a programming issue, not a language issue. All languages can easily represent rational numbers as canonicalized pairs of integers: J happens to have them built-in. If you need to deal with non canonicalized pairs, it is easy to do that too, although this is not built-in in J. The matrix similarity questions I mentioned needs the programmer to keep in mind the ring over which the similarity is being constructed. I do not see how the language is going to do that for you.
